Description

PCB board surface defect detection device with turn over board function Technical Field The utility model relates to the technical field of detection equipment, in particular to a PCB surface defect detection device with a turning plate function. Background A PCB, i.e. a printed circuit board, is an indispensable core component in modern electronic devices, which provides electrical connection and mechanical support for electronic components by means of organic bonding of conductive paths to an insulating substrate. In the production process, in order to ensure that the surface of the PCB is defect-free, detection equipment is generally required to be used for comprehensively detecting the surface of the PCB. Currently, the detection devices on the market are mainly divided into a single board detection device and a continuous detection device, and the two types of detection devices have advantages and disadvantages. When the single board detection equipment is used, the PCB to be detected is fixed in the special fixture, and passes through the scanning camera in a uniform speed transmission mode, and finally, a scanning image is displayed on the display for an operator to analyze and judge. It should be noted that the PCB boards can be classified into a single panel type and a double panel type according to structures. When detecting the double-sided board, the scanning of one side is usually required to be completed firstly, then the other side is detected after the double-sided board is manually turned over and re-fixed, the process is complicated, the detection efficiency is reduced, and errors can be introduced due to manual operation.
